A person who often uses overused or clichéd statements instead of original thoughts.
The speaker was criticized for being a platitudinarian, as he relied on tired phrases instead of offering new ideas.
Platitudinarian → It is formed from "platitude" (from French *platitude*, meaning flatness or dullness) and the suffix "-arian" (meaning one who practices or is related to). The word describes a person who is characterized by or indulges in flat, dull, or trite remarks.
Think of someone who speaks in a flat or dull manner ('platitude') and is related to that style of speaking ('-arian'). This helps you remember that a platitudinarian is someone who often uses unoriginal or trite expressions.
